Loop bonding (also know as inverse multiplexing) allows multiple physical lines to be grouped together in order to achieve higher data rates. For example, you can use two 2.3Mbps SHDSL lines to provide up to 4.6Mbps. Loop bonding requires no extra configuration, and is an easy way to increase line speeds where extra copper is available. Net to Net Technolgies can loop bond 2 x ADSL lines or up to 12 x SHDSL lines.
